-# Given a list of filenames on the command line or on stdin this
-# script returns the interpreter that is required to run the
-# filenames. Usually this is extracted from the #! line of the file
-# but we also handle the various 'exec' tricks that people use to
-# start the interpreter via an intermediate shell.
-
-# Also we want to convert:
-# /usr/local/bin/perl5.00404
-# /usr/local/bin/tclsh8.0
-# into dependencies with RPM version numbers.
-
-
-
-
-
-# These have all been seen on our system or are "recommended" in
-# various man pages.
-
-# Examples:
-
-# #!/bin/sh
-# # the next line restarts using wish \
-# exec wish "$0" "$@"
-
-
-# #!/bin/sh -- # -*- perl -*- -p
-# eval 'exec /usr/bin/perl -wS $0 ${1+"$@"}'
-# if $running_under_some_shell;
-
-
-# #!/bin/sh -- # -*- perl -*- -p
-# eval '(exit $?0)' && eval 'exec /usr/bin/perl -wS $0 ${1+"$@"}'
-
-
-# #!/bin/sh -- # -*- perl -*- -p
-# & eval 'exec /usr/bin/perl -wS $0 $argv:q'
-# if $running_under_some_shell;
-
-
-# #! /usr/bin/env python
